Green Gobbler Fruit Fly Killer+ - Kills Fruit Flies, Drain Flies & Sewer Flies, Gel Treatment for Use in Sinks & Pipes - Safe for Septic Systems, 32oz - Up to 8 USES (2 Pack)

I ordered Green Gobbler because of the previous reviews. I did a lot of research on how to get rid of drain flies and this one seemed to have the best results. UPDATE: It works. Followed the instructions which were very simple and happily the treatment worked. They are gone and will continue with a monthly treatment from now on.

Worked immediately. Terrific product, would totally buy it again. I tried 3 traps, none caught a single fruitfly. I put this stuff I'm my drain with about 15 of them flying around my sink. Went back 2/2 hour later no fruitflies at all I haven't seen a fruitfly since.

Works well but you need to use often.

No matter the product consistency is key to getting rid of drain flies. Do it daily until they are gone. I found using this along with the liquid traps worked the best

Living in an apartment gnats come through the drain. This product eliminates that! Large bottle will last a long time l. The product is thick enough to stick to the pipes when poured in the drain. It has a scent but I can’t describe it.

Normally, I love this brand but I'm really upset about this product that's supposed to take care of fruit flies and sewer flies. Instructions state that leaving it in the drain overnight is ideal so that's what I did. They also say that for best results, use it several times so I repeated the process the next night. Both times, I wiped away the excess with paper towel since rinsing them wasn't an option. So, not only has it eaten the finish off of my drain (or whatever the correct term is), this morning there were several sewer flies. I am not a happy girl. So, this is an update. I contacted the Green Gobbler customer service folks copying the review above and since they had no way for me to attach the pictures below, I described what had happened. I received back a boilerplate email describing that some drains are tougher to unclog than others. Really? I write about a product designed to rid your drains of fruit and sewer flies and they respond with info about unclogging my drains? I responded telling them that I was disappointed that they hadn't even taken the time to read my comment. Pretty poor and what's worse is that they did not respond to then at all to me. I'm just disgusted as I have used their drain cleaner several times and it's done a great job but this has soured me on the company.

Worked well

Product works as designed.
